From Wikipedia: Toma lived under the name András Tamás (Андраш Тамаш). A Czech linguist of Slovak descent, Karol Moravčík, identified him as Hungarian, and on 11 August 2000, Toma arrived back in Hungary where his family was identified through DNA matching. Since he was never discharged, Toma was promoted to sergeant major by the Minister of Defense, and since his military service had been continuous, his decades of accumulated unpaid salary were paid in full.

At least they didn’t screw him out of his military pension.
